Answer:

x=\frac{12.5-b}{a}

Step-by-step explanation:

ax+b=12.5\\\\ax+b-b=12.5-b\\\\ax=12.5-b\\\\\frac{1}{a}*ax =\frac{1}{a}*(12.5-b)\\\\x=\frac{12.5-b}{a}

Evaluate intergral 10xe exponent 10x dx​
Shtirlitz [24]

Answer:

for this type of question, integral by parts should be used . This involves using the formula for intregation by parts:

intudv=uv-intvdu.  

lets first break apart the x and e10x into two parts - "u" and "v"

where u = x.

however, we need to find the value of v. in order to do this, we can integrate dv/dx in order to get to v.  

the value of dv/dx is : e10x

 

u = x             dv/dx = e10x

 

as seen in the formula, you need to have a value for u, dv, v and du.  

therefore in order to get du you must differentiate u:

u = x    

du/dx = 1

du = 1dx = dx

du = dx

 

in order to get v you need to integrate dv/dx:

\displaystyle \inte10x dx = 1/10 x10x

now that we have both parts, we can put this back into the formula.  

 

intudv=uv-intvdu.  

 

\displaystyle \intxe10x = x * 1/10e10x  - \displaystyle \int1/10e10x dx

Solve for u. 20 − (u · 0.9) = 4.7
alina1380 [7]

Answer:

20 - 0.9u = 4.7

-0.9u = 4.7 - 20

-0.9u = -15.3

Divide both sides by - 0.9

u = 17

Hope this helps.
